Abstract：
A double superlayer of MRPC with 2×5-gas gaps has been tested at CERN-PS (T10) beam line. The prototype has the sensitive area of 200mm×63mm with 2×6 readout pads, which are connected geometrically in series and electrically in parallel. The 45ps time resolution at more than 99% efficiency can be obtained for the 7GeV/c negative pions after the T-A correction.
